Abstract

A secure telephone call management system is provided for authenticating users of a telephone system in an institutional facility. Authentication of the users of the telephone call management system is accomplished by using a personal identification number, biometric means, and/or radio frequency means. The secure telephone call management system includes accounting software capable of limiting access to the system based on funds in a user's account, and includes management software capable of implementing widespread or local changes to the system. The system monitors a conversation in the telephone call to detect a presence of a first characteristic in audio of the conversation, and terminates the telephone call if the first characteristic does not match a second characteristic of biometric information of a user or a called party.

First claim

What is claimed is:

1 . A system, comprising:
a voice sample database; and a control platform configured to:
receive a voice sample from a user;
store the voice sample in the database;
receive identifying information related to the user; and
store the identifying information in the database in correspondence with the voice sample.

2 . The system of claim 1 , wherein the voice sample is a standardized phrase spoken by the user.

3 . The system of claim 1 , wherein the voice sample is a name of the user as spoken by the user.

4 . The system of claim 1 , wherein the voice sample is a portion of a telephone conversation.

5 . The system of claim 4 , wherein the portion of the telephone conversation corresponds to a predetermined duration of an initial portion of the telephone conversation.

6 . The system of claim 1 , wherein the control platform is further configured to:
receive second information related to the user; and store the second information in the database in correspondence with the voice sample.

7 . The system of claim 6 , wherein the second information includes at least one of an identification number, a name of the user, a phone number, a phone number of a party to be called, or a language preference.

8 . The system of claim 1 , wherein the identifying information includes a personal identification number.

9 . The system of claim 1 , wherein the identifying information includes a name of the user.

10 . The system of claim 1 , further comprising:
an authentication module configured to:
receive a second voice sample from a second user;
receive second identifying information related to the second user;
find in the database third identifying information that substantially matches the second identifying information received from the second user;
retrieve from the database a third voice sample associated with the third identifying information;
compare the second voice sample with the third voice sample; and
authenticate the second user based on the comparison.

11 . A method, comprising:
receiving a request to connect a phone call from a local party to a called party; connecting to the called party; requesting a voice sample from the called party; comparing the voice sample with a stored voice sample; determining, based on the comparison, that the voice sample is a statistical match to the stored voice sample; and allowing the local party and the remote party to converse only after the determination.

12 . The method of claim 11 , wherein the voice sample is a standardized phrase spoken by the called party.

13 . The method of claim 11 , wherein the voice sample is a name of the called party as spoken by the called party.

14 . The method of claim 11 , wherein the determining includes determining that the voice sample and the stored voice sample correlate to within a pre-assigned statistical threshold.

15 . The method of claim 11 , wherein the voice sample and the stored voice sample are compared using speaker-dependent voice recognition.

16 . A method, comprising:
receiving a request to connect a phone call from a local party to a called party; connecting to the called party; searching a voice sample database for a voice sample of the called party; determining that there is no voice sample of the called party stored in the voice sample database; in response to the determination, requesting a voice sample from the called party; storing the voice sample in the voice sample database; and allowing the local party and the remote party to converse.

17 . The method of claim 16 , wherein the voice sample is a standardized phrase spoken by the called party.

18 . The method of claim 16 , wherein the voice sample is a name of the called party as spoken by the called party.

19 . The method of claim 16 , wherein the voice sample database indexes stored voice samples by the phone number of the called party.

20 . The method of claim 16 , wherein the voice sample database indexes stored voice samples by the name of the called party.
